"We landed at Keflavik and drove to our Airbnb in Hafnarfjordur, then decided after 2 pm to drive over to and hike up Esja. It won’t be that hard, I thought; it’s not even 1,000 meters and we hike peaks close to 2,000 meters every year in North Carolina. However, it was raining lightly and windy the entire hike and we were both jet-lagged. We went up about 3 km and decided to turn around. My wife was feeling miserable and mad at me for pushing onward. She had broken her foot a year ago but it was hurting now. She made the right call. Loved the dramatic scenery. We also saw many locals hiking up in running clothes as if it were just another blustery day, which it was for them." — tlannin • Jul 28, 2019

"Beautiful day ,the route to keilir lies from Vogar Vatnsleysustrond which is between Reykjavik the capital of Iceland and Keflavik.. once we got to the parking space it is 6-8 kilometers walk from there to the mountain and a bit of that is over old Lava .. it was windy and the mountain is steep but taking small steps up the mountain and a lot of breaks (a bit of loose gravel )should get you to the top :)" — jonpeturkristjansson • Aug 16, 2014

"Went alone ,it is a fairly easy walk / climb taken from the left side seen from the valley of Mosfellsdalur . it gives a good view of the surrounding area which is the town of Mosfellsbaer on the left looking at the sea and Mount Esja on the right :)" — jonpeturkristjansson • Aug 10, 2000
